What does business chain BTB mining mean

1.

In 2009, bencong invented bitcoin, and set that there are only 21 million bitcoins. By participating in the proction of blocks and providing proof of work (POW), he can get the reward of bitcoin network. This process is mining

the concept of "mining" comes from the existing concepts in our real economic life, such as gold mining and silver mining. Because minerals are valuable, it drives people to pay labor to dig

another important point of bitcoin mining is that the miners who participate in mining recognize the value of bitcoin, and some of them are willing to spend money in the bitcoin market. Therefore, the mining of bitcoin is meaningful

extended data

currency characteristics of bitcoin

1, decentralized

bitcoin is the first distributed virtual currency, and the whole network is composed of users without central bank. Decentralization is the guarantee of bitcoin's security and freedom

2, bitcoin can be managed on any computer connected to the Internet. No matter where you are, anyone can dig, buy, sell or collect bitcoin

3, exclusive ownership

controlling bitcoin requires a private key, which can be stored in any storage medium in isolation. No one can get it except the user himself

4, low transaction cost

bitcoin can be remitted free of charge, but in the end, about 1 bitfen transaction fee will be charged for each transaction to ensure faster transaction execution

5, no hidden cost

as a means of payment from a to B, bitcoin has no cumbersome limit of quota and proceres. If you know the other party's bitcoin address, you can pay

6, cross platform mining

users can explore the computing power of different hardware on many platforms

2.

Bitcoin mining is a process that uses computer hardware to calculate the location of bitcoin and obtain it

mining is an incentive process to record data in the bitcoin system. In the bitcoin system, indivial users have the right to pack blocks after calculating a specific hash value by using CPU or GPU to hash

and in order to reward this user for packing blocks, the system will give a certain amount of bitcoin as reward. Because this process is very similar to "mining" in real life, most people call this process mining. In addition to bitcoin, other electronic virtual currencies can also be obtained through mining rewards, such as Ethereum, Monroe and so on

extended data:

mining risk:

1, currency security

the withdrawal of bitcoin requires hundreds of keys, and most people will record this long string of numbers on the computer, but frequent problems such as hard disk damage will make the key permanently lost, which also leads to the loss of bitcoin

2, system risk

system risk is very common in bitcoin, and the most common one is bifurcation. Bifurcation will lead to a drop in currency price and a sharp drop in mining income. However, many cases show that the forking will benefit the miners, and the forked competitive currency also needs the miners' computing power to complete the minting and trading process. In order to win more miners, the competitive currency will provide more block rewards and handling charges to attract miners. Risk makes miners

3.

Mining means that users download software from personal computers and then run specific algorithms to get corresponding bitcoin after communicating with remote servers

bitcoin is a kind of network virtual currency. Internet users can use bitcoin to buy some virtual goods, such as clothes, hats and equipment in online games. Internet users can also use bitcoin to buy real goods

bitcoin mining system is the process of carrying out mathematical operation for bitcoin network through computer hardware, and the miners who provide services can get a reward, because the network reward is calculated according to the tasks completed by the miners, so the competition for mining is very fierce

bitcoin mining started with low-cost hardware such as CPU or GPU, but with the popularity of bitcoin, the mining process has changed greatly. Nowadays, the mining activities are transferred to the field programmable gate array, and the hash speed can be achieved through optimization. The mining efficiency of this mode is very high

extended materials:

the founder of bitcoin:

on November 1, 2008, a person who called himself Satoshi Nakamoto posted a research statement on a secret cryptography review group, stating his new idea of e-money - bitcoin came out and the first transaction of bitcoin was completed

bitcoin has got rid of the constraints of third-party organizations with the help of Internet, which Nakamoto calls "regional chain". Users are willing to dedicate the computing power of CPU and run a special software to be a "digger", which will form a network to maintain the "regional chain". In the process, they also generate new money

trading is also extended on this network. The computer running this software can solve the problem of irreversible code, which contains several trading data

the first "miner" to deal with the problem will be rewarded with 50 bitcoin, and the relevant trading area will join the chain. As the number of "miners" increases, the difficulty of each puzzle also increases, which keeps the proctivity of bitcoin in each trading area at about 10 minutes

in 2009, Nakamoto designed a digital currency, namely bitcoin. The booming bitcoin market has gone up and down, and the identity of its founder "Nakamoto" has always been a mystery. Rumors about "the father of bitcoin" involve from the US National Security Agency to financial experts, and also give bitcoin a mysterious aura

BTB generally refers to bromothymol blue, bromothymol blue, also known as bromothymol blue. BTB for short. Bromothymol blue is a kind of acid-base indicator and adsorption indicator. In biological experiments, it is often used as a respiratory reagent for aquatic organisms

{rrrrrrr}

< H2 > extended data

experimental effect of bromothymol blue:

in biological experiments, it is commonly used as a respiratory reagent for aquatic organisms, and the life of organisms in water containing this reagent for a short time has no effect, and the water added with 0.1% BTB solution generally appears light green. If the carbon dioxide content in the water increases and becomes acidic, the water will change from light green to yellow

However, the accuracy is higher than that of lime water, and there is no interference of SO2. Bromothymol blue aqueous solution can identify carbon dioxide (CO2), and the solution changes from blue to green and then to yellow

when BTB reagent meets alkaline solution, it will form blue solution, and when BTB reagent meets acidic solution, it will form yellow solution

6. I'm not sure you didn't, but your risk of infection is relatively reced. In addition, whether Xiumei knife has been disinfected or not, I suggest you test again in 8 weeks. If it's negative, your risk of infection is less than 0.5%. To make sure you don't, it's best to have a test in three months..

7. B2B (business
to
business) is the exchange of procts, services and information between enterprises through the Internet. At present, the development of B2B based on the Internet is very fast. According to the latest statistics, at the beginning of this year, the transaction volume of B2B on the Internet has far exceeded that of B2C. In the next five years, B2B will reach an average annual growth rate of 41%. By 2004, the global B2B transaction is expected to reach $7.29 trillion
the traditional transaction between enterprises often consumes a lot of resources and time, and takes up the cost of procts whether it is sales and distribution or procurement. Through B2B transaction, buyers and sellers can complete the whole business process on the Internet, from establishing the initial impression, comparing three goods to bargaining, signing and delivery, and finally to customer service. B2B makes the transaction between enterprises rece a lot of transactional workflow and management costs, and reces the operating costs of enterprises. The convenience and extension of the network make the enterprise expand the scope of activities, the development of enterprises across regions and borders more convenient, and the cost is lower
B2B is not only to establish an online group of buyers and sellers, but also to provide a basis for strategic cooperation between enterprises. It is impossible for any enterprise to realize B2B alone, no matter how strong its technical strength or how good its business strategy is. The era of fighting alone has passed, and the establishment of cooperative alliance among enterprises has graally become a development trend. The network makes the information flow unimpeded. Enterprises can establish complementary and mutually beneficial cooperation in market, proct or operation through the network, form horizontal or vertical business integration, and truly achieve the mode of global operational research management with larger scale, stronger strength and more economic operation< At present, B2B adopted by enterprises can be divided into the following two modes:
1.
manufacturing oriented or business oriented vertical B2B. Vertical B2B can be divided into two directions, namely upstream and downstream. Manufacturers or commercial retailers can form supply relations with upstream suppliers. For example, Dell computer company cooperates with upstream chip and motherboard manufacturers in this way. Manufacturers and downstream distributors can form a sales relationship, such as the transaction between Cisco and its distributors<
2. This kind of transaction mode is horizontal B2B. It concentrates the similar transaction process in various instries into one place and provides a transaction opportunity for the purchasers and suppliers of enterprises, such as Alibaba, global resource network, etc
B2B is just the beginning of e-commerce, its application will be continuously developed and improved, and adapt to the needs of enterprises in all instries< At present, enterprises need the support of many systems to realize perfect B2B, such as financial system, ERP system, SCM system, CRM system and so on. These systems can be organically integrated to realize information sharing and complete automation of business process.

Considering the characteristics of these enterprises, Xinnet provides enterprises with affordable B2B e-commerce solutions
on the one hand, enterprises can use the procts provided by the new network to realize B2B step by step from low-end to high-end, from single to comprehensive. For example, distributors can use the new network's DRP system according to the main characteristics of business, commercial enterprises can use the new network's SCM system, and enterprises focusing on sales, services and other businesses can use the CRM system
on the other hand, considering the financial and personnel constraints of some small and medium-sized enterprises, Xinnet will provide enterprise users with Internet-based software hosting, distribution, management application leasing and related services in the form of ASP application software service providers. Enterprise users can fully entrust the infrastructure, business operation and application management required by business applications to application service providers such as Xinnet. It enables users to get high-quality technology and service guarantee in the way of low-cost investment, so as to ensure the smooth implementation of enterprise e-commerce strategy
B2B is the best entry point for enterprises to realize e-commerce and promote business development. The most direct benefit for enterprises is to rece costs and improve efficiency, which can also bring huge returns in the long run. Compared with the past, more and more attention has been paid to the combination with information technology in the overall strategy of enterprises. The CEOs of the company realize that they must do something to maintain the competitiveness of the enterprise. Information technology is increasingly vital to enterprises. New information technology investment can really enhance the strength of enterprises, not limited to improving their daily operation.
